Transmission for electric vehicle

A transmission apparatus for a vehicle, including:

• a deceleration device coupled to a motor shaft and an input shaft and receiving power from the motor shaft and decelerating a rotation speed of the motor shaft and outputting the power to the input shaft;
• an output shaft disposed in parallel with the input shaft;
• a hollow shaft provided on the input shaft and rotatable with respect to the input shaft;
• a clutch device provided to selectively switch a transmission state of the power from the input shaft to the hollow shaft;
• a first synchronizer fixed to the input shaft;
• a second synchronizer fixed to the hollow shaft;
• a plurality of driving gears having different sizes and rotatably provided on the input shaft and the hollow shaft to be engaged with at least one of the first synchronizer and the second synchronizer;
• and
• a plurality of driven gears fixedly provided on the output shaft to be engaged with the plurality of driving gears to form different shift ratios, respectively.
